im looking at 2006 m.jet 120 doblo owner says car has white smoke on hard acceleration , he says and i quote New EGR 2 months ago New TURBO 2 months ago and a new AIR flow meter same time, sounds like he was chasing said problem, does any one have a clue what problem might be, and how serious it might be to fix/ diagnose . thanks in advance mike.

white smoke indicates unburnt fuel,a strong smell of diesel is a good indication of this.
having the same issue on my old astra head gasket had to be replaced.

thanks,if in doubt walk away i think..... did not think these jtd engines were prone to cylinder issues.

You are right, they are indeed a good strong engine, but i would walk away if it was me there are plenty to choose from,happy hunting.
